ALFRED R. PULLIN, OF SYDNEY, NEW SOUTH WVALES, AUSTRALIA.

SIGN OR SIGNAL.

SPECIFICATION forming part of Letters Patent No. 369,615, dated September 6, 1887.

Application filed May13,1887. Serial No. 23am. (No model.)

To all whom it may concern:

Be it known that I, ALFRED R. PULLIN, a subject of the Queen of Great Britain, residing at Sydney, in New South Wales, Australia, have invented certain new and useful Im' provements in Signs or Signals; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improvement in signs or signals; and it consists in certain features of novelty in the construction and arrangement of a system of signs or signals adapted more particularly for advertising or signalizing in the day-time,and more especially in cases where it is desired that the advertisement or signal may be seen at long distances, substantially as will be hereinafter described and claimed.

In the annexed drawings, illustrating my invention, Figure 1 is aside elevation of my improved sign or signaling device. vFig. 2 is a sectional top plan view of the same. Fig. 3 is a detail perspective of a few of the flaps and the mechanism for operating them. Fig. 4 is a top edge view of a number of the flaps, together with a diagram showing their path of movement. 7

Like letters of reference denote like parts in all the figures.

The framework-which is used in connection with the mechanism constituting myimproved signaling devices consists, essentially, of the vertical board or partition A, of rectangular form, surrounding which is a suitable frame consisting, for example, of the upper and lower horizontal bars, B and B, and the vertical end connections, 0 C. It is obvious that the structure and arrangement of the bars, 850., which constitute this frame-work, may be varied, if desired, the arrangement that is shown in the drawings being used by way of example.

On each side of the board A is arranged a series 01' swinging flaps or leaves, D and D.

These flaps are in general of a rectangular form, and they move with relation to board A, as shown by the dotted lines in Figs. 3 and 4.. On these flaps are inscribed or delineated the letters, names, pictures, signs, or other devices of advertisement or signaling. They are pivoted at top and bottom, so as to swing in the manner specified. This pivoting is effected by means of a rod secured to the inner vertical edge of the flap and extending above and below the same, so as to enter looselythe bars B and B, or by other equivalent means. It is evident that there may be any number of these flaps to suit the purpose for which the device is used. Further, it may be said that the flaps D on one side of the board A are preferably opposite to the flaps D on the other side of said board.

Underneath the series of flaps D is arranged a horizontal bar, E, having a series of upwardly-projecting pins, 6, that enter slots 1) in the bottom edges of the flaps D. Underneath the series of flaps D there is also arranged a similar horizontal bar, E, having upwardly-projecting pins 6, that enter slots in the bottom edges of the flaps D. These bars E E are pivotally connected at their ends to cross-bars F F. that are pivoted centrally to the bar B. To one end of one of these cross-bars is pivoted a connecting-rod, G, the other end of which is attached to a crank, H, which is adapted to be rotated by suitable means. The rotation of the crank will oscillate the cross-bars F F upon their central pivots and impart an endwise movement to the bars E and E, which will result in causing the flaps or ribs to rotate or swing right and left, alternately, through an arc of one hundred and eighty degrees, thus alternately eXposing'the two plane surfaces ofthe flaps upon which are inscribed or painted names, pictures, or advertisements, as above mentioned.

Having thus described myinvention,what I claim as new, and desire to secure by Letters Patent, is

1. In a sign or signal, in combination with a stationary frame, one or more signs or flaps pivoted to the frame near their rear vertical edges and adapted to vibrate and present opposite sides to view, and having ornamental or advertising matter thereon, and 1nechanism directly connected to and vibrating such flaps, as set forth.

2. In a sign or signal, the combination of a stationary frame having a background or par- ICO tition and one or more flaps pivoted near their rear vertical edges to said frame and adapted to vibrate therein, so as to form aflat surface when nearing the limit of vibration, whereby opposite sides are presented to view, and having ornamental or advertising matter thereon, with a mechanism directly connected to and vibrating such flaps, substantially as described.

3. In a sign or signal, the combination of the vertical partition, the frame surrounding said partition, the series of swinging flaps on each side thereof, and means for swinging said flaps, consisting of horizontal bars having pins that enter slots in the bottom edges of the flaps, said bars being pivotally connected to pivoted cross-pieces and operated bya crankconnection, substantially as described.

4. The combination of partition A, upper In testimony whereof I affiX my signature in presence of two witnesses.

ALFRED R. PULLIN.
